I don't know anything specific about plasma tv's, but it's probably something to do with how the tv displays colors. Maybe when its white, it's using up the most power? Usually noises are hard to fix unless its an easy to replace component.

I have never hooked up a PC to either of my plasmas, nor have I ever heard strange noises coming from them. Is it the speaker? In regards to whites... I did have an old TV that would buzz when there was a lot of white on the screen.

I have heard plasmas buzz a lot displaying different things on the screen, older ones in particular. I have read that altitude plays a factor as well, but haven't been around one at high altitude to experience this.

Only time i can hear noise coming from my panny plasma is when i turn the volume down, can hear a slight whirl of the fans - its still pretty quiet though. I have heard a buzz on some models though, probably the power supply. Also, as far as I know Pioneer has stopped production on their plasma lineup.
